Parts marked with “” are important for maintaining the safety of the set. Be sure to replace these parts with
specified ones for maintaining the safety and performance of the set.
This document has been published to be used
for after sales service only.
The contents are subject to change without notice.
This Service Manual uses some photographs to assure safe operation.
Please understand the meanings of photographs before servicing.
WARNING: If this WARNING should be ignored, a serious danger
to life or a serious injury may result.
CAUTION: If this CAUTION should be ignored, injury or damage
to property could result.
1. Warning for servicing
1) Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.
Avoid complex wiring, which may lead to a fire or an electric shock.
2) If there is any abnormality such as smoke or an abnormal smell,
interrupt the job and disconnect the power plug.
It may cause a fire or an electric shock.
3) Be sure the machine is properly grounded. Failure to ground the
machine properly may result in an electric shock or fire.
To protect the machine and the power unit from lightening, grounding must be made.
4) When connecting the ground wire, never connect it to the following
points as it may cause an explosion, fire, or an electric shock:
• Gas tube
• Lightning conductor
• A water pipe or a water faucet, which is not recognized as a
grounding object by the authorities.
• Grounding wire for telephone line
5) Do not damage, break, or stress the power cord. Do not put heavy
objects on the power cord. Do not bend or pull the cord forcefully. It
may cause a fire or electric shock.
6) Keep the power cable away from a heat source.
Do not insert the power plug with dust on it into a power outlet.
It may cause a fire or an electric shock.
7) Do not put a receptacle with water in it or a metal piece which may
drop inside the machine.
It may cause a fire or an electric shock.
8) Do not touch the power plug, insert a telephone jack, perform service or operate the machine with wet or oil hands. It may cause an
electric shock.
2. Precautions for servicing
1) When servicing, disconnect the power plug, the printer cable, the
network cable, and the telephone line from the machine, except
when performing the communication test, etc.
It may cause an injury or an electric shock.
2) There is a high temperature area inside the machine. Use extreme
care when servicing.
3) There is a high voltage section inside the machine which may
cause an electric shock . Be careful when servicing.
4) Do not disassemble the laser unit. Do not insert a reflective material such as a screwdriver in the laser beam path.
It may damage eyes by reflection of laser beams.
5) When servicing the machine while operating, be careful not to
make contact with chains, belts, gear, and any other moving parts.
6) Do not leave the machine with the cabinet disassembled.
Do not allow any person other than a serviceman to touch inside
the machine. It may cause an electric shock, a burn, or an injury.
7) When servicing, do not breathe toner, developer, and ink excessively. Do not get them in the eyes.
If toner, developer, or ink enters you eyes, wash it away with water
immediately, and consult a doctor if necessary.
8) The machine has got sharp edges inside. Be careful not to damage fingers when servicing.
9) Do not throw toner or a toner cartridge in a fire. Otherwise, toner
may pop and burn you.
10) When replacing the lithium battery on the PWB, use only the specified battery. If a battery of different specification is used, it may not
be compatible and cause breakdown or malfunction of the
machine.
11) When carrying an electric unit or a PWB, use an anti-static (electricity) bag. Failure to do so may cause component failure or
machine malfunction.
3. Note for installing site
Do not install the machine at the following sites.
1) Place of high temperature, high humidity, low temperature, low
humidity, place under an extreme change in temperature and
humidity.
Paper may get damp and form dews inside the machine, causing
paper jam or copy dirt.
For operating and storing conditions, refer to the specifications
described later.
2) Place of much vibrations
It may cause a breakdown.
3) Poorly ventilated place
An electro-static type copier will produce ozone inside it.
The quantity of ozone produced is designed to a low level so as
not to affect human bodies. However, continuous use of such a
machine may produce a smell of ozone. Install the machine in a
well ventilated place, and ventilate occasionally.
4) Place of direct sunlight.
Plastic parts and ink may be deformed, discolored, or may undergo
qualitative change.
It may cause a breakdown or copy dirt.
5) Place which is full of organic gases such as ammonium
The organic photoconductor (OPC) drum used in the machine may
undergo qualitative change due to organic gases such as ammonium.
Installation of this machine near a diazo-type copier may result in
dirt copy.
6) Place of much dust
When dusts enter the machine, it may cause a breakdown or copy
dirt.
7) Place near a wall
Some machine require intake and exhaust of air.
If intake and exhaust of air are not properly performed, copy dirt or
a breakdown may be resulted.
8) Unstable or slant surface
If the machine drops or fall down, it may cause an injury or a breakdown.
If there are optional paper desk and the copier desk specified, it is
recommendable to use them.
When using the optional desk, be sure to fix the adjuster and lock
the casters.

The set value is received from the digital copier, and data are made
according to the set value.
∗ Left margin
Since the paper size sensor is not set, the digital copier cannot recognize the size and direction of paper which is actually inserted.
Therefore, the left margin is set according to the paper size specified in
the print data sent from the computer, and print process is performed.
If the computer does not specify the paper size, or in the case of the
custom size, the left margin is set according to the default paper size.
(7) Print reference
This machine employs the center reference system.
Since the digital copier is not provided with the tray size detection feature, formatting and center distribution are performed not by the actual
paper size but by the paper size specified by the computer.

D. System outline
The GDI-PWB is provided with IEEE1284 I/F on the host side, and the
16-bit bi-directional data bus I/F and UART on the machine side. Transfer of image data with the IMC-PWB is performed with this 16-bit bidirectional data bus. Command status information with the engine is
processed with UART.
This unit is installed to the position of PCL-PWB on the conventional
AR-235/ 275.
JBIG compression data sent from the host are transferred to the IMC
PWB, where the data are extracted to be VIDEO data, and sent
through the MCU PWB to the LSU.

[5] UNPACKING AND INSTALLATION
1. Installation
A. Environment
The performance of this machine is affected by the environment of the
installing site. Avoid installation to the following places:
• Avoid installation in direct sunlight, otherwise the plastic parts may
be deformed.
• Avoid installation to a place where there is ammonium gas.
Installation near a diazo-copier may lead to dirty copy.
• Be sure to have enough space around the machine.
Be sure to allow the required space around the machine for servicing
and proper ventilation.
12" (30cm)
• Avoid installation in a place of high temperature, high humidity, low
temperature or low humidity, otherwise paper may be dampened and
frost may be generated in the machine to cause a paper jam and
dirty copy.
• Avoid installation in a dusty place, otherwise dust may enter the
machine to cause dirty copy or machine troubles.
• Avoid installation to a place with much vibration, otherwise the
machine may cause troubles.

B. Power source
• Be sure to use only the power outlet (with the earth terminal) of 15A
or more and 100V.
• Install the machine near the power outlet to facilitate disconnection
of the power plug.
• If the power plug of this machine and other illuminating apparatus
are connected to the same power outlet, the lamp may flicker. Use
an exclusive power outlet for this machine without connecting
another lamp together.
• Avoid complex wiring. Be careful not to damage, break, or process
the power cord.
• Earth wire connection
Be sure to connect the earth wire for protection against danger.
If not, improper grounding may cause a fire or an electric shock.
• Avoid installation to a place of poor ventilation.
